zephyr: Build MicroPython as a cmake target.
Refactors the zephyr build infrastructure to build MicroPython as a cmake target, using the recently introduced core cmake rules. This change makes it possible to build the zephyr port like most other zephyr applications using west or cmake directly. It simplifies building with extra cmake arguments, such as specifying an alternate conf file or adding an Arduino shield. It also enables building the zephyr port anywhere in the host file system, which will allow regressing across multiple boards with the zephyr twister script.

With Zephyr installed you may then need to configure your environment,

for example by sourcing `zephyrproject/zephyr/zephyr-env.sh`.

Once Zephyr is ready to use you can build the MicroPython port.
|

In the port subdirectory `ports/zephyr/` run:
|
||||
Once Zephyr is ready to use you can build the MicroPython port just like any
|
||||
other Zephyr application. You can do this anywhere in your file system, it does
|
||||
not have to be in the `ports/zephyr` directory. Assuming you have cloned the
|
||||
MicroPython repository into your home directory, you can build the Zephyr port
|
||||
for a frdm_k64f board like this:
|
||||
|
||||
$ make BOARD=<board>
|
||||
$ west build -b frdm_k64f ~/micropython/ports/zephyr
|
||||
|

If you don't specify BOARD, the default is `qemu_x86` (x86 target running
|
||||
in QEMU emulator). Consult the Zephyr documentation above for the list of

||||
To build for QEMU instead:
|
||||
|
||||
$ west build -b qemu_x86 ~/micropython/ports/zephyr
|
||||
|
||||
Consult the Zephyr documentation above for the list of
|
||||
supported boards. Board configuration files appearing in `ports/zephyr/boards/`
|
||||
correspond to boards that have been tested with MicroPython and may have
|
||||
additional options enabled, like filesystem support.
|
||||
|
||||
|
||||
Running
|
||||
-------
|
||||
|
||||
To flash the resulting firmware to your board:
|
||||
|
||||
$ west flash
|
||||
|
||||
Or, to flash it to your board and start a gdb debug session:
|
||||
|
||||
$ west debug
|
||||
|
||||
To run the resulting firmware in QEMU (for BOARDs like qemu_x86,
|
||||
qemu_cortex_m3):
|
||||
|
||||
make run
|
||||
$ west build -t run
|

With the default configuration, networking is now enabled, so you need to

follow instructions in https://wiki.zephyrproject.org/view/Networking-with-Qemu
|

to setup host side of TAP/SLIP networking. If you get error like:

Networking is enabled with the default configuration, so you need to follow
|

instructions in
|
||||
https://docs.zephyrproject.org/latest/guides/networking/qemu_setup.html#networking-with-qemu
|

to setup the host side of TAP/SLIP networking. If you get an error like:
|
||||
|
||||
could not connect serial device to character backend 'unix:/tmp/slip.sock'
|
||||
|
||||
it's a sign that you didn't followed instructions above. If you would like
|
||||
it's a sign that you didn't follow the instructions above. If you would like
|
||||
to just run it quickly without extra setup, see "minimal" build below.
|
||||
|
||||
For deploying/flashing a firmware on a real board, follow Zephyr
|
||||
documentation for a given board, including known issues for that board
|
||||
(if any). (Mind again that networking is enabled for the default build,
|
||||
so you should know if there're any special requirements in that regard,
|
||||
cf. for example QEMU networking requirements above; real hardware boards
|
||||
generally should not have any special requirements, unless there're known
|
||||
issues).
|

|

For example, to deploy firmware on the FRDM-K64F board run:

$ make BOARD=frdm_k64f flash
